.NAME
DiskAccessPath .DESCRIPTION The resource is used to initialize, format and mount the partition/volume to a folder access path. The disk to add the partition/volume to is selected by specifying the DiskId and optionally DiskIdType. The DiskId value can be a Disk Number, Unique Id, Guid, Location or FriendlyName. **Important: The Disk Number is not a reliable method of selecting a disk because it has been shown to change between reboots in some environments. It is recommended to use the Unique Id if possible.** The Disk Number, Unique Id, Guid, Location and FriendlyName can be identified for a disk by using the PowerShell command: `powershell Get-Disk | Select-Object -Property FriendlyName,DiskNumber,UniqueId,Guid,Location ` Note: The Guid for a disk is only assigned once the partition table for the disk has been created (e.g. the disk has been initialized). Therefore to use this method of disk selection the disk must have been initialized by some other method. ## Known Issues ### Null Location The Location for a disk may be null for some types of disk, e.g. file-based virtual disks. Physical disks or Virtual disks provided via a hypervisor or other hardware virtualization platform should not be affected. .PARAMETER AccessPath Key - String Specifies the access path folder to the assign the disk volume to. .PARAMETER NoDefaultDriveLetter Write - Boolean Specifies no automatic drive letter assignment to the partition: Defaults to True .PARAMETER DiskId Required - String Specifies the disk identifier for the disk to modify. .PARAMETER DiskIdType Write - String Allowed values: Number, UniqueId, Guid, Location, FriendlyName Specifies the identifier type the DiskId contains. Defaults to Number. .PARAMETER Size Write - UInt64 Specifies the size of new volume. .PARAMETER FSLabel Write - String Define volume label if required. .PARAMETER AllocationUnitSize Write - UInt32 Specifies the allocation unit size to use when formatting the volume. .PARAMETER FSFormat Write - String Allowed values: NTFS, ReFS Specifies the file system format of the new volume. .EXAMPLE 1 This configuration will wait for disk 2 to become available, and then make the disk available as two new formatted volumes mounted to folders c:\SQLData and c:\SQLLog, with c:\SQLLog using all available space after c:\SQLData has been created.
